Abstract
A hollow concrete composite plate foundation of coal mine subsidence area transmission tower used for an ultra-high voltage transmission line in a coal mine subsidence area comprises a flexible concrete individual foundation disposed under the support leg of the iron tower, a sliding layer and a hollow concrete composite plate disposed under the flexible concrete individual foundation in sequential order. The integration of the tower foundation is enhanced, the subsidiary stress on the transmission tower caused by the vertical and horizontal deformation of the earth's surface can be reduced to enable the tower to withstand the influence of the mining, so that the safety of the transmission tower is guaranteed. The opening in the composite plate has advantages of good economical effect, simple structure, strong deformation stability, and convenient construction.
Description
Technical field
The utility model relates to a kind of concrete slab basis, is particularly useful for the transmission tower hollow concrete composite plate basis, subsidence area, colliery that subsidence area, colliery extra high voltage network uses.
Background technology
Along with the construction of near coal-mine power plant and the continuous development of electrical network, increasing transmission line of electricity need pass through minery.On the other hand,, have a strong impact on the safety of existing extra high voltage network shaft tower, ultra-high-tension power transmission line on subsidence area (minery) and pylon have been caused very big threat and harm along with the expansion of underground mining scope.Therefore, carried out the research on minery resistance to deformation basis, colliery in recent years, proposed the strong composite protective plate base of non-deformability, the safety of guaranteeing high-voltage transmission line pole tower has been had significant values.
But along with the fast development of China's EHV transmission transmission line of electricity, pylon is more and more higher, and root is opened increasing, causes the area of composite protective plate base also increasing, and the expense of Zeng Jiaing is more and more higher thus.The environmental problem that while large tracts of land excavation causes is more and more outstanding.Therefore, improve existing composite protective plate base, when guaranteeing high-voltage transmission line pole tower safety, reduce its cost, alleviate, have important economy and environment protection significance environment damage.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of non-deformability strong, and construction is simple, the transmission tower hollow concrete composite plate basis, subsidence area, colliery of economy, environmental protection.
For achieving the above object, transmission tower hollow concrete composite plate basis, subsidence area, colliery of the present utility model comprises and is located at the flexible concrete single footing of propping up the underfooting at the iron tower pylon, be sequentially with sliding layer, concrete slab and sand cushion under the flexible concrete single footing, have hole in the middle of the described composite plate.
Described sliding layer is made of sand pebble layer; Described sliding layer is made of the layers of asphalt malthoid that is lined with layer of sand; Described sliding layer is made of one deck polyfluortetraethylene plate.
Beneficial effect: the globality that composite plate of the present utility model basis can increase tower foundation, effectively reduce the subsidiary stress that vertical surface deformation and horizontal distortion produce on transmission tower, make its influence that can stand to adopt, guarantee the safety of transmission tower; The composite plate good economy performance that punches, few to environment damage, simple in structure, non-deformability is strong, and it is convenient to construct, and has practicality widely.

Fig. 1 is colliery of the present utility model subsidence area transmission tower and Hollow composite board foundation structure figure.
Fig. 2 is subsidence area, a colliery of the present utility model transmission tower Hollow composite board plan view.
Among the figure: 1-iron tower pylon, 2-flexible concrete single footing, 3-sliding layer, 4-concrete slab, 5-sand cushion, 6-hole.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
As shown in the figure: transmission tower Hollow composite board basis, subsidence area, colliery of the present utility model, form by iron tower pylon 1, flexible single footing 2, sliding layer 3, concrete slab 4, sand cushion 5.The 2 times orders in flexible concrete single footing are provided with sliding layer 3, concrete slab 4 and sand cushion 5, the centre of concrete slab 4 has the hole 6 of tangible Hollow composite board, concrete slab 4 thickness are between 200mm～700mm, and the thickness of sand cushion 5 is greater than 300mm.Wherein sliding layer 3 is made of sand pebble layer, also can by the layers of asphalt malthoid that is lined with layer of sand or one deck polyfluortetraethylene plate constitutes.
The course of work: after at first reaching projected depth according to designing requirement excavation ground, adopt medium sand construction sand cushion 5, compaction in layers reaches design thickness, construct successively again and leave steel concrete composite plate 4, sliding layer 3, the flexible single footing 2 of hole 6, after 2 constructions of flexible single footing are finished, iron tower pylon 1 is installed.
